-IN CHECK LIST OF THE LEPIDOPTERA OF BOREAL AMERICA, SUPERFAMILIES SPHINGOIDEA, SATURNIOIDEA, AND BOMBYCOIDEA of the Families Syntomidse and Arctiidse WM. BARNES and F. H. BENJAMIN, Decatur, Illinois INTRODUCTION The present list is a continuation of our Check List of the Diurnal Lepidoptera of Boreal America. The same general introductory re-marks apply. Considerable time and energy has been expended during the past two years in an effort to eliminate as many errors as possible; and there has been much communication with practically all institutions containing specific types of the organisms involved. We wish to again issue our warning that lists are only tentative, and contain many errors. For example, we have endeavored to learn the exact status of the names applied by Professor M. Draudt in the genus Cisthene. The types of these, with the exception of costimacula (see B. & Benj., 1926, Ins. Insc. Menst., XIV, 1), are presumably in the British Museum being the specimens listed by Hampson, 1900, Cat. Lep. Phal. B. M., II, as "ab. 1", etc., mostly under the name "Illice unifascia." We are greatly indebted to Mr. Tarns for many kind-nesses, one of the least of which was an attempt to place these names. As yet we are not certain of the status of any of them. Pro-fessor Draudt has informed us that he did not see the specimens to which he applied names. Following our Diurnal List we use the following markings to indicate certain facts usually omitted from check lists, but which numerous friends assure us are of decided value. * indicates that the organism does not occur, or is of decidedly doubtful occurrence, within the fauna we are considering. t means an unavailable name, usually a homonym.
